본 고안은 편향요크에 관한 것으로서, 보다 상세하게는 음극선관의 네크부에 견고히 설치될 수 있도록 한 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly to a deflection yoke that can be installed firmly in the neck portion of the cathode ray tube.
편향요크는 음극선관의 네크부에 설치되어 전자총을부터 방출되는 전자빔임을 최종적으로 화면상에 편향시켜 주는 부품으로서, 구 주되 구조는 나팔모양의 세퍼레이터 내측에 배치되어 전자비임을 수평방향으로 편향시키는 수평편향코일과, 세퍼레이터 외측에 배치되어 전자비임을 수지방향으로 편향시키는 수직편향코일로 되어있다.The deflection yoke is a part installed at the neck of the cathode ray tube to deflect the electron beam emitted from the electron gun finally on the screen. The deflection yoke is arranged inside the trumpet-shaped separator to horizontally deflect the electron beam in the horizontal direction. A deflection coil and a vertical deflection coil disposed outside the separator to deflect the electron beam in the resin direction.
상기한 수평 및 수직편향코일은 통전에 의해 비임의 진행통로상에 자계를 형성함으로서 비임을 편향시키게 되는데, 이때 편향요크의 위치에 따라 편향점이 변화되므로 편향요크는 부동의 자세로 설치되는것이 바람직하다.The horizontal and vertical deflection coils deflect the beam by forming a magnetic field on the propagation path of the beam by energization. In this case, the deflection yoke is preferably installed in a floating posture because the deflection point changes according to the position of the deflection yoke. .
종래에는 편향요크를 음극선관의 편넬부에 설치하기 위한 수단으로 편향요크의 네크부 내측에 테이프를 개재시켜 클램프로 고정하였다.Conventionally, the clamp is fixed by clamping the deflection yoke through a tape inside the neck of the deflection yoke as a means for installing the deflection yoke in the channel portion of the cathode ray tube.
그러나 이러한 고정방식은 편향점을 찾기 위하여 화면을 디스플레이 시키는 경우에 음극선관의 네크브가 가열되면 테이프가 점성을 잃게 되므로 편향요크가 뒤로 밀리는 현상이 나타나 편향점이 틀려지는 문제점이 있다.However, this fixing method causes the tape to lose viscosity when the neck of the cathode ray tube is heated when the screen is displayed in order to find the deflection point, so that the deflection yoke is pushed backward and thus the deflection point is wrong.
게다가 화면을 디스플레이시킨 상태에서 편향점을 찾은후에 편향요크를 고정시켜야 하므로 ITC 작업이 지연되는 한 요인이 되고 있다.In addition, the deflection yoke needs to be fixed after finding the deflection point while the screen is displayed, which is one factor that delays ITC work.
본 고안은 상기한 바와같은 종래기술의 문제점을 해소하기 위하여 안출된 것으로서, 고정설치가 용이하고 확고하게 고정할 수 있는 편향요크를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a deflection yoke that can be fixed and fixed easily.
이를 실현하기 위하여 편향점과 일치하는 음극선관의 네크부 외주상에 원주방향으로 돌기를 형성하고, 이 돌기가 삽입되는 홈을 네크부 내주면에 형성하여 그 외주면을 클램프로 고정시킬 수 있도록한 편향요크를 제공한다.To realize this, a deflection yoke is formed in the circumferential direction on the outer circumference of the neck of the cathode ray tube corresponding to the deflection point, and a groove into which the projection is inserted is formed on the inner circumference of the neck to fix the outer circumferential surface with a clamp. To provide.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라서 더욱 상세히 설명한다. 제1도는 본 고안의 편향요크 요부 사시도로서, 부호(1)(2)은 나팔체의 세퍼레이터를 지칭한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 is a perspective view of a deflection yoke main portion of the present invention, and reference numerals 1 and 2 refer to separators of the trumpet body.
세퍼레이터(1)(2)는 편향코일(도시생략)이 내외측에 배치되는 깔때기부(3)(4)와 단자판(도시생략)이 내외측에 배치되는 깔때기부(3)(4)와 단자판(도시생략)이 설치됨과 아울러 보정철편(도시생략)이 설치되는 플랜지부(5)(6)와 클램프가 조여지는 네크부(7)(8)로 이루어져 있다.The separators 1 and 2 are funnel portions 3 and 4 with deflection coils (not shown) disposed inside and outside, and funnel portions 3 and 4 with terminal plates (not shown) disposed inside and outside. (Not shown) and flange portions (5) (6) on which correction iron pieces (not shown) are installed, and neck portions (7) (8) on which clamps are tightened.
상기한 네크부(7)(8)는 클램핑시 음극선관의 판넬부에 밀착고정될 수 있도록 다수개로 분할되어 있다.The neck portions 7 and 8 are divided into a plurality of pieces so that they can be tightly fixed to the panel portion of the cathode ray tube during clamping.
네크부(7)(8)의 내주면에는 홈(9)(10)이 원주방향으로 형성되어 있다.Grooves 9 and 10 are formed in the circumferential direction on the inner circumferential surface of the neck portions 7 and 8.
제2도는 본 고안의 편향요크가 음극선관에 고정설치된 상태를 나타내는 도면으로서, 음극선관의 네크부(N)에는 돌기(P)가 형성되어 있으며, 이 네크부(N) 외측으로는 편향요크(Y)의 네크부(7)(8)가 삽입되어 있다.2 is a view showing a state in which the deflection yoke of the present invention is fixed to the cathode ray tube, and a projection P is formed at the neck portion N of the cathode ray tube, and the deflection yoke (outside the neck portion N) is formed. The neck portions 7 and 8 of Y) are inserted.
이러한 조립으로 네크부(7)(8)의 홈(9)(10)에 음극선관의 돌기(P)가 삽입위치하게 되며 네크부(7)(8)의 외측에는 클램프(11)가 조여지게 된다.This assembly causes the projection P of the cathode ray tube to be inserted into the grooves 9 and 10 of the necks 7 and 8, and clamps 11 to the outside of the necks 7 and 8. do.
상기한 돌(P)는 편향요크(Y)가 설치되었을때 편향점이 정확하게 맞는 위치가 될 수 있어야 한다.The stone (P) should be able to be the exact position of the deflection point when the deflection yoke (Y) is installed.
이와같이 구성된 본 고안은 음극선관에 편향요크(Y)를 고정시킬때 네크부(N)에 삽입시키게 되면 홈(9)(10)에 돌기(P)가 위치하게 된다.When the present invention configured as described above is inserted into the neck portion N when the deflection yoke (Y) is fixed to the cathode ray tube, the projections (P) are positioned in the grooves (9) and (10).
이러한 상태에서 클램프(11)를 네크부(7)(8)에 끼우고 조이면 조립이 간단하게 된다.In this state, assembling and clamping the clamp 11 to the neck portions 7 and 8 simplifies assembly.
이와같이 조립되는 편향요크는 음극선관의 돌기(P)에 걸리는 상태가 되므로 뒤로 밀리지 않게되어 견고한 고정상태를 유지할 수 있으며, 이러한 고정상태는 돌기(P)에 의해 편향점이 일치하게 되므로 ITC작업시 화면을 디스플레이 시키지 않아도 된다.The deflected yoke assembled in this way is caught in the projection (P) of the cathode ray tube so that it is not pushed back to maintain a firm fixed state. This fixed state is the same as the deflection point by the projection (P), so that the screen during ITC work You do not need to display it.
이상 설명한 바와 같이 본 고안의 편향요크는 음극선관에 삽입한 상태에서 돌기와 홈의 위치만을 일치시킨후 클램프를 조이게 되면 편향점이 정확하게 될 뿐만 아니라 견고히 고정되므로 편향점이 변형되는데에 따른 제반 문제점을 해소할 수 있다.As described above, the deflection yoke of the present invention is not only accurate in the deflection point but also firmly fixed by tightening the clamp after only matching the position of the projection and the groove in the state of being inserted into the cathode ray tube, thereby eliminating all problems caused by the deformation of the deflection point. have.
